Flavia Albia, daughter of Marcus Didius Falco, has taken over her father's business as a private informer. She only has two hard and fast rules - avoid political cases and family cases because nothing good comes of either of them. Unfortunately, since Albia isn't good at avoiding either, it's really more of a guideline. So when her Aunt Junia demands Albia track down a couple of deadbeats who owe her money, it's an offer Albia can't refuse.

It turns out to be a relatively easy job, requiring only some half-hearted blackmail, and it leads to some new work - tracking down some essential paperwork for the debtor family. But nothing is truly easy in Rome - if Albia doesn't find the paperwork that proves that family's ancestor was a properly freed slave, the family could lose everything. The more she digs, the more skeletons she finds in their closet, until murder in the past leads to murder in the present. Now, it's serious, even deadly, and Albia has precious little time to uncover the
truth.
